King SI-Series rod bearings are recommended for OE applications. These
rod bearings are designed for aftermarket gasoline or diesel engine
rebuilding and performance engines with OE crankshafts. These King
SI-Series rod bearings have an improved finish for reducing microscopic
ferrite peaks on improperly ground or polished nodular cast iron
crankshafts. These King SI-Series rod bearings feature improved oil
clearance to reduce wear and increase engine life, which in turn reduces
operating noise, vibration, and excess oil flow.
